Abstract

Thurston related CP1\mathbb{C}{\rm P}^1-structures (complex projective structures) and equivariant pleated surfaces in the hyperbolic-three space H3\mathbb{H}^3, in order to give a parameterization of the deformation space of CP1\mathbb{C}{\rm P}^1-structures. In this note, we summarize Thurston's parametrization of CP1\mathbb{C}{\rm P}^1-structures, based on Kamishima-Tan and Kulkani-Pinkall. We, in addition, give independent proofs for the following well-known theorems on CP1\mathbb{C}{\rm P}^1-structures by means of pleated surfaces given by the parameterization. (1) Goldman's Theorem on CP1\mathbb{C}{\rm P}^1-structures with quasi-Fuchsian holonomy. (2) The path lifting property of developing maps in their domains of discontinuity in CP1\mathbb{C}{\rm P}^1.
